RECTAL sPEcuLuivi.

SPECIFICATION forming part of Letters Patent No. 302,846, dated July 29,1884.

Application filed March 19, 1884. (No model.)

To all whom it may concern.-

Be it known that I, LUTHER J. INGERSOLL, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented a new and useful Rectal Speculum, of which the followingis a specification,reference being had to the accompanying drawings.

This invention has relation to speculums for use in treating rectaldiseases; and it consists in the construction and novel arrangement ofparts, as will be hereinafter fully described, and particularly pointedout in the claims appended.

Figure l is a perspective view of the improved speculum closed. Fig. 2is a similar view showing the speculum open and the upper opening of theinner tube registering with the upper opening of the outer or incasingtube of the speculum. Fig. 3 is a perspective view of the inner tubedetached from the inclosingtube, and Fig. 4 is a vertical sectionalview. Fig. 5 is a vertical section showing the slide in the inner shell.

Referring by letter to the accompanying drawings, a designates the outershell of the speculum, which tapers from its mouth or base slightly, asshown, leaving the rounded closed top larger than is customary in thisclass of speculums.

Near the upper or closed end of the shell (1, I provide an opening, 12,preferably of the v shape shown in Figs. 1 and 2, and below thisopening, and continuing to the mouth of the speculum, is a slot, 0,extending about onehalf of the length of the shell a, which is closedand opened, when necessary, by a slide, d, fitted therein, and providedwith a suitable finger-piece by which to work it. This shell a isprovided with a handle, e, and around its mouth with an internal groove,f, which receives the end of a pin, g, by which the revoluble innershell, h, is secured in place within the outer shell, a. The innershell, h, tapers similarly to the outer shell, and has also a roundedclosed top, and a handle, 1', by which to turn it in the shell a. Nearits upper end the inner shell, h, is provided with an opening, is, whichis intended to register with the upper opening in the outer shell toopen it at times. On the opposite side of this shell h, near its upper{end, commencing some distance lower down than the upper end of theopening 7c, is a second elongated opening, Z, extending down nearly tothe mouth of the shell h.

Above the opening Z, and extending from the top of the opening it in thedirection of the opening Zdownward, is an inclined metal deflector, m.

This speculum can be used with less discomfort to the patient than thosein which a slide extends throughout the entire length of the shell. Toopen the upper orificeit is not necessary to draw the slide out, as theinner shell can be revolved within the outer shell to open and closethem. The elongated opening 1 in the inner shell is cut away in order togive as much room as possible through which to treat the affected parts,and for examining the rectum without increasing the circumference of thespeculum. The speculum is a little larger at the point than thoseordinarily used, and for this reason shows to better advantage the partsof the rectum at the point of the speculum. The parts of the rectum tobe examined protrude within the speculum when the slide or orifices areopen, and also when they are being treated. It is evident that the slidemay be used in the inner revoluble speculum-shell, and the opening bemade in the outer shell. The inclined plate in the upper end of theinner shell is not only a reflector, but serves also as a deflector, toguide a pludget of medicated cotton or the like to the part to betreated. The slide need not be provided with a handle, as it can bemoved in and out without it, and is in the operators way when thespeculum is being used.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

The combination, with the tapering closedtop shell a, having the openingb near its top in one side, and the slot 0, communicating therewith,provided with theslide d, of the tapering closed-top shell 71., providedwith the opening it near its top in one side, and the slot Z below inthe opposite side, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
